Unfortunately, I am leaving in February for good.

I am happy that I managed to ski Mt. Fuji in May even though it was a brutal 7-8 hours up and ~2 min down.

Alphaod, if you are a bunch of people, rent a large car, be flexible and drive around to check out different mountains. I guess the majority prefer the expensive resorts, but you will get much more of an adventure and also experience more Japanese culture at these other places.
